6.6 SERVICE TEST MODE

1. Configuration and conditions during checking
• Emergency shut down will not happen even if breakdown happens in the Service Test mode. (Just ignore it)
• POWER ON in test mode can be done in less than 1 minute even when emergency shut down happens when error is
detected.
• Total power on time can be checked.
2. Switching to the Test Mode
• AC power on when the STEST port (pin 43) is set to HIGH (5 V).
∗ Initial function is DVD/CD.
• AC power on by pressing the STOP key and POWER key on the front panel at the same time.
The set will automatically power on and the following display will appear.
• The FL display during TEST MODE entry is different depending on whether NORMAL POWER OFF occurred before
entering the TEST MODE or EMERGENCY SHUT DOWN occurred due to error detection.
